Every year Russell-Zuhl participates in the Tucson Gem and Mineral Show – a show dedicated to presenting extraordinary mineral exhibits to the public.

It is here at this show that we exhibit some of our most treasured specimens of petrified wood for public display. As the shows offers a combination of museum and shopping experiences, attendance provides you with a unique opportunity to closely inspect these geological wonders, considered to be some of the world’s finest petrified wood specimens. Where else could you view ancient trees that lived over 220 million years ago, brilliantly preserved by hard quartz?

Our petrified wood expert, Ralph, will be attending, giving you the chance to speak face-to-face with the most experienced excavator, cutter and polisher of petrified wood in the world.

It is a not-to-be-missed event for those who share a fascination with the earth’s most precious gifts, whether you are a professional or amateur collector, nature lover, interior designer, or museum curator.
